MINI-VCI J2534 DLL

J2534 library for MVCI devices

Overview

This library implements the J2534 API for use with XHorse MINI-VCI (and clone) devices.

It was built with the MinGW GCC compiler on Linux. Testing was done using Wine and Windows 10 64-bit. The only external dependencies are the C runtime and standard Windows libraries, therefore I would not expect any major problems building with other compilers.

Registry values

In accordance with the J2534 API specification, the values identifying the DLL to applications are stored under the HKEY_LOCAL_MACHINE\Software\PassThruSupport.04.04\XHorse - MVCI key.

There are several values under the Parameters subkey that can be used to control the behaviour of the DLL:

• Comport - the number of the COM serial port the device is connected to (if using the Win32 Comm functions). Required if UseD2XX parameter (see below) is zero.
• USBDescription - the USB description string of the device (used to open a handle to the device when using FTDI D2XX functions). Defaults to "M-VCI" if not set.
• UseD2XX - if set to non-zero (boolean TRUE), use the FTDI D2XX library to communicate with the device; if zero (boolean FALSE), use Win32 Comm functions. It's recommended to use D2XX on Windows and Comm functions on Linux. Defaults to zero if not set.
